In the test test_tablet_mv_replica_pairing_during_replace we stop 2 out of 4 servers while using RF=2. Even though in the test we use exactly 4 tablets (1 for each replica of a base table and view), intially, the tablets may not be split evenly between all nodes. Because of this, even when we chose a server that hosts the view and a different server that hosts the base table, we sometimes stoped all replicas of the base or the view table because the node with the base table replica may also be a view replica. After some time, the tablets should be distributed across all nodes. When that happens, there will be no common nodes with a base and view replica, so the test scenario will continue as planned. In this patch, we add this waiting period after creating the base and view, and continue the test only when all 4 tablets are on distinct nodes.

If you can use an existing folder, consider adding your test to it. New folders should be used for new large categories/subsystems, or when the test environment is significantly different from some existing suite, e.g. you plan to start scylladb with different configuration, and you intend to add many tests and would like them to reuse an existing Scylla cluster (clusters can be reused for tests within the same folder).
To add a new folder, create a new directory, and then
copy & edit its suite.ini.
